Solution Overview

Problem

Existing matching services often fail to connect individuals who may be compatible based on deep psychological traits and interests, as they focus solely on self-identified preferences, potentially limiting potential matches.

Innovation Solution

A matching system that correlates user profiles based on a relaxed set of self-identified preferences, calculates compatibility values, and incorporates deep psychological traits, using a neural network to optimize matching, allowing for broader potential matches by relaxing importance levels or preferences if initial matches are insufficient.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the matching service focuses solely on self-identified preferences, then the matching criteria are clear and easy to implement, but potential compatible matches are missed because deep psychological traits are not considered

Engineering Contradiction:
Improveease of implementationVSAvoidmatching accuracy
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The matching system segments compatibility assessment into multiple dimensions: self-identified preferences (explicit criteria) and deep psychological traits (implicit criteria). By dividing the matching process into these separate but complementary components, the system can maintain clear implementation guidelines while incorporating comprehensive compatibility factors that improve matching accuracy without overwhelming complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary analysis layer that processes user behavior data, interaction patterns, and psychological indicators to infer deep traits. This intermediary component bridges the gap between simple self-identified preferences and complex compatibility assessment, enabling the system to consider psychological dimensions without requiring direct user input for every factor

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If the matching service uses a relaxed set of preferences to identify more potential matches, then the pool of compatible users expands, but the precision of matching criteria decreases

Engineering Contradiction:
Improvenumber of potential matchesVSAvoidmatching precision
Core Design Contradiction:
Quantity of substanceVSMeasurement precision

Solution Approach 1:

The system dynamically adjusts matching parameters by applying different weightings to various compatibility factors. For users seeking a relaxed approach, the system increases the weight of deep psychological traits while reducing the strictness of self-identified preference filtering. This parameter adjustment allows the system to expand the potential match pool while maintaining precision through adaptive criterion weighting rather than fixed thresholds

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system implements a two-stage matching process: first, a broad screening phase that considers a relaxed set of preferences to identify a larger pool of potential matches, then a refinement phase that applies more precise compatibility assessment. This partial application of strict criteria initially, followed by deeper analysis, enables the system to cast a wide net while maintaining matching precision through subsequent filtering and ranking

Inventive Principle:
Principle #16Partial or excessive action

AI summary

The field of the invention relates to systems and methods for operation of a matching service, and more particularly to systems and methods that enable online compatibility matching and ranking. In a preferred embodiment, the system includes a matching system server coupled to a public network and accessible to one or more users. The matching system server includes a database that stores match profile data associated with the one more users, wherein the match profile data includes self-identified preferences. The matching server system is configured to correlate a first user's match profile data with one or more of the plurality of users' match profile data to identify a set of potential matches for the first user based on a relaxed set of self-identified preferences and calculate a compatibility value for each match in the set of potential matches.
